In PreTranslateMessage, i am calling DoModal function (to show the dialog box) and then it is showing the dialog box and after clicking on the OK button it is giving the Debug Assertion Failed error.

error is as follows:
Debug Assertion Failed!
Program:..xxxx
File:afxwin2.inl
Line:265

what is the cause of this error?

can we do like this?

Sample Code is :
BOOL CTry1::PreTranslateMessage(MSG* pMsg)
{
...
...
CMyDialog DlgObj;
DlgObj.DoModal();

return CDialog::PreTranslateMessage(pMsg);

}

it is giving error while executing the last line 'return CDialog::PreTranslateMessage(pMsg);'.

Needs your code to answer. Better yes, look by yourself under debugger.

What line is the debugger stopping on? The assert usually tells you something about what it checked that was invalid.

it is giving debug assertion error while executing the following line
"return CDialog::PreTranslateMessage(pMsg);"

before this line i am calling DoModal function of the CMyDialog class.

What does the assert line assert though?

BOOL CWnd::PreTranslateMessage(MSG* pMsg)
{
// handle tooltip messages (some messages cancel, some may cause it to popup)
AFX_MODULE_STATE* pModuleState = _AFX_CMDTARGET_GETSTATE();
if (pModuleState->m_pfnFilterToolTipMessage != NULL)
(*pModuleState->m_pfnFilterToolTipMessage)(pMsg, this);

// no default processing
return FALSE;
}

it is giving error for the following line in above code
(*pModuleState->m_pfnFilterToolTipMessage)(pMsg, this);

you're still not answering my question... what does the assert say? ... should say something like ASSERT(hWnd!=NULL); or something like that
